Light cover for an elongate illumination system

Abstract

A light cover for an elongate illumination system has a substantially planar, elongate light-emitting element and securing strips provided on the longitudinal sides of the light-emitting element, the securing strips being provided for securing the light cover to a light housing. The light-emitting element and the securing strips are made of different materials and the material of the securing strips is more flexible than the material of the light-emitting element.

The invention claimed is: 
     
       1. A light cover for an elongate illumination system, comprising:
 an essentially planar plate-shaped, elongate light emission element; and 
 fastening profiles, which are arranged on longitudinal sides of the light emission element for fastening the light cover on a light housing said fastening profiles being integrally formed with the light emission element; 
 wherein the light emission element and the fastening profiles consist of different materials and the material of the fastening profiles is more flexible than the material of the light emission element. 
 
     
     
       2. The light cover as claimed in  claim 1 , wherein the fastening profiles extend over the entire length of the light emission element. 
     
     
       3. The light cover as claimed in  claim 1 , wherein the fastening profiles each form one or more webs, which are at least partially aligned essentially perpendicularly to the plane of the light emission element. 
     
     
       4. The light cover as claimed in  claim 1 , wherein the light emission element consists of PMMA or PC. 
     
     
       5. The light cover as claimed in  claim 1 , wherein the fastening profiles consist of a thermoplastic elastomer. 
     
     
       6. The light cover as claimed in  claim 1 , wherein the light emission element has light-scattering properties. 
     
     
       7. The light cover as claimed in  claim 1 , produced by a coextrusion method. 
     
     
       8. The light cover as claimed in  claim 1 , wherein at least one surface of the light emission element is provided with a structure. 
     
     
       9. The light cover as claimed in  claim 8 , wherein the structure is formed by a film, which is glued onto the light emission element. 
     
     
       10. The light band system comprising:
 an elongate housing having light sources located therein, and 
 a light cover as claimed in  claim 1 .
